Final answer:
African Americans and Hispanics are highly clustered in urban areas in the Classic Northern model and the New City model.
Step-by-step explanation:
The two scales that African Americans and Hispanics are highly clustered in urban areas are the Classic Northern model and the New City model.
In the Classic Northern model, African Americans dominate the inner cities of the Industrial Midwest and Northeast. Cities like Cleveland, Detroit, Chicago, and Milwaukee have high levels of segregation index scores. This model shows high levels of black ghettoization in cities with Classic Northern style ghettos.
In the New City model, ghettos in automobile-friendly locations, like Los Angeles, Dallas, and Phoenix, tend to be linear and stretch along highways outward from downtown. In some cities, Latin American and Asian groups also create additional linear ghettos along important highway corridors extending from the central business district (CBD).
